Results from logistic regression multiple imputation analysis.

Preterm delivery is defined as a woman’s most preterm delivery prior to her first MI. Hypertensive disorders of pregnancy are defined as a woman’s most serious diagnosis prior to her first MI.

Model I includes adverse pregnancy outcome history; age at first time MI [continuous].

Model II additionally includes diabetes [yes/no]; hypertension [yes/no]; treatment for dyslipidemia [yes/no]; smoking status [never smoker, current smoker, ex-smoker >1 month]; BMI [continuous].

BMI = body mass index; MI = myocardial infarction.
